AUTOMATIC GRAIN WEIGHER AND REGISTER.

SPECIFICATION forming part of Letters Patent N o. 394,440, datedDecember 11, 1888.

Application tiled June 28, 1888. Serial No. 278,390. (No model.)

To all whom it may concern.-

Be it known that we, JOHN K. BENDER and JOSEPH H. BINGMAN, citizens ot'the United States,and residents of Highland,in the county of vDoniphanand State of Kansas, have invented certain new and useful Improvementsin Automatic Grain lVeighers and Registers; and we do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilledin the art to which it appertains tomake and use the same, reference beingI had to the aecompanyingdrawings, and to letters or figures of reference marked thereon, whichform a part ot this speci'lication.

Figure l of the drawings is a representation of our improvement and is aside view thereof, and Fig. 2 is a top or plan view.

The invention relates to improvements in automatic grain weighers andregisters; and it consists in the construction and novel combination ofparts, as hereinafter set forth.

The object ot' the invention is to provide a machine that is not liableto become choked or clogged by grain, as there are no valves or smalltubes in its construction.

Referring to the drawings, A designates the casing, consisting ot' theend walls, a, and the curved side walls, a. An inclined chute, B, opensoutwardly from the bottom and the device is supported on the legs l).

C is the weighing-beam, extending outwardly through a slot, b', in theside of the casing. The said beam is properly graduated into pounds andfractions thereof, and the adjustable weight c may be secured at anypoint on the beam by means of the setscrew c.

The beam has its portion within the casing branched and forming the armsD, which extend along the side wall, and then outwardly at right angles,as at (I, to the cent-er of the end walls. crumed on pivots in thebearings (I, secured to the inner side of the end walls. E is thegrain-weighing box,di vided into two V-shaped sections, l1 l1", by thecentral partition, e, and the box has pivotal bearings fin the ends ofthe arms l). (.)ne oi' said bearings extends outwardly through aslot-opening in the end wall of the casing, and is formed with the crankf.

The pivots f are secured to the outer ends of the weighing-box in linewith the central partition, but somewhat above the bottom The arms D areful.`

line of the box, so that the bottom of the section F or F being filledwith grain is at one side of the pivotal center. lVhen the box isdepressed by the grain in the section, the greater weight is at one sideof the pivotal point and turns the box on its pivots, allowing the grainto escape into and out of the chute and presenting the mouth of theother section to the grain coming from the elevator. The curved arms K,secured to the bottom ot' the box, are designed by coming in contactwith the transverse bar L in the casing to limit the movement of theweighing-box, and the said arms are preferably of spring material, so asto relieve the parts from a direct shock. The curved detents G on theouter side of the weighing-box alternately bear against 011e of therollers H, pivoted in bearings secured to the inner side of the casing,as shown. These detents, in connection with the rollers, hold thesections in proper positions to be iilled, and when the necessaryamountof grain falls in the section to balance the weight the box isforced downward till the detent comes below the roller, when the boxautomatically turns and dumps the grain.

The register l may be of any desired construction, and to this part ofthe machine we make no claim. The lever i, which operates the register,is connected to the crank f by the rod j, and it obvious that upon everyturn of the weighing-box the crank will turn the register one point.

A door may be hinged or otherwise placed over the opening at the top ofthe casing.

Having described my invention, what I claim isl. The combination, withthe casing, the transverse bar L, an d the weighing-box, of the curvedspring-arms K, secured to the bottom of said box, substantially asspecified.

2. The combination, with the weighingbox, consisting of the V-shapedsections, the

case, and the weighing-beam, oi' the bearing extending through a slotopening in t-he casing, and having a crank portion and theconnecting-rod, substantially as specified.

In testimony whereof we affix our signatures in presence ot' twowitnesses,
